Don Ferreyra
Don Ferreyra was able to play complex musical pieces without and instrument. He mimiced the flute using just his mouth and hands.
Ferreyra was Portuguese, and seems to have performed in England in the late-1860s before making his way to American.
He can be found playing both dime museums and concert halls, and even travelled with a few different minstrel shows.
In an odd coincidence, there is a contemporary Argentinian sax/flute player with the name Luis Ferreyra who performs today.
